The “Janta Board” series of products is low cost minimum features affordable starter kit range.
The word “Janta” is from “Hindi” language (India’s National Language).
“Janta” is normally refereed as common man.
Thus we thought if making starter kit for common man.
There are “Janta Boards” for 8051, AVR, PICs and this one for ARM LPC2138.
The product is built around ARM7 LPC2138 .
The EM-JB-LPC2138 provides basic setup of hardware like power supply, JTAG Port, 6 pin Programming Port, DBG jumper, BSL Jumper and male headers for I/O ports.
The LPC2138 can be programmed via JTAG port or via ISP Port
In either case, the Programmer is not included with the product.
USB Programmer for LPC ARM and P89XXX can be used to program the LPC2138 via USB port.
This Programmer is not included in the product list.

Not able to flash Hex file using the ARM7 programmer.
Downloaded the driver and I can see the USB COM Port (COM 10) in my device manager...
However none of the LEDs on the programmer is on and when I try to connect through flash magic it can not connect to the device.
Made the ISP connection right; connected all pins except VCC as per the instruction. The Janta Board is on (green LED) with 9V power supply
Please let me know how to debug the issue.
Thanks

1. Which OS are you using?
2. There are 2 Jumpers on the ARM USB Programmer. Pl specify it's settings.
3. What is the exact Error Message shown by FlashMagic?

There could be the problem of wrong FTDI drivers selected. Do check the OS & it's suitable driver on FTDI site.

I have installed the driver and tested the circuit both on windows vista
and XP.
A red Led and a green Led is glowing on the programmer but no led glows on
janta board.
Pls help me out

There are 2 jumpers on the USB-LPC-89V Programmer. One is 2 pin and other is 3 pins. Keep the 2 pin Jumper OPEN. Set the 3 Pin Jumper to LPC Side. Read the small font text carefully. Connect Programmer to PC using USB Cable. Connect 9V DC Power to the LPC2138 Janta Board. Make connections between the programmer & the LPC board as described in the user manual. Re-read all above steps, you must be missing something, I guess power to the LPC board and 2 Pin jumper.

Can I use 12V Input for the board?

The voltage regulator IC will get heat up due to higher difference in input & output voltages.
